2 ）對新生代龍門山前陸盆地大邑礫巖巖相、沉積相和沉積環境進行了系統分析和研究，劃分出6種粗碎屑巖相、 5種中碎屑巖相、 3種細碎屑巖相，確定了大邑礫巖為沖積扇相、河流相沉積環境的組合。 -
By studying the lithologjcal and mineral parameters ( pebbled elastics percent ratio, clastic maturation index, heavy crop stability factor ) of mesozoic sedimentary strata, the result shows that the northern boundary of present basin is near to the boundary of original basin and the moving distance of elastics is short, but the southern boundary of present basin is far from the boundary of original basin and the moving distance of elastics is long. the fades of northern basin are mainly delta fades and the fades of middle and southern basin are lacustrine fades
通過對盆地中生代沉積地層中各種巖礦參數（碎屑巖含礫百分比、碎屑成熟度指數和重礦物穩定系數）分析和綜合研究認為，今盆地北部距離原始盆地沉積邊界較近，碎屑物搬運距離較短；南部距離盆地古沉積邊界較遠，沉積物搬運距離較遠；中生代盆地北部主要為三角洲沉積相，中南部為湖泊相沉積。
